EDWARD DE lVITT MASON, OF BUFFALO, NEW YORK.

MOVABLE COAL-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 245,531, dated August 9, 1881.

Application filed June 20, 1881. (No model.)

To all whom it may concern Be it known that I, EDWARD DE. \VITT MA- SON, a citizen of the United States, residing at Buffalo, in the county'of Erie and State of New York, have made certain Improvements in Movable Coal-Elevators, of which the following is a specification.

This invention relates to a device to be used on coal-wharves or elsewhere for elevating and delivering coal, &c., from piles into vessels, can al-boats, 850., to save hand-labor and wheeling in barrows, 850.; and the invention consists in the combination of parts for this pun pose; also, in the construction of the elevatorbucket and a telescopic spout, all as hereinafter fully explained.

In the drawings, Figure 1 is a side elevation, showing one end of the truck with the derrick-frame thereon, supporting the elevatingleg, the hopper, and part of the conveyer attached at the other side. Fig. 2 is a perspective of a part of the conveyer and of the weighhopper; Fig. 3, perspective of the coal-bucket; and Fig. 4, side elevation,in section, ofthetelescopic spout.

A A represent a substantial frame-work or derrick on a truck, B, having wheels at both ends and sides to move the device either way on a track or ground.

At the top of one side of the frame A is attached an elevating frame or leg, G, carrying endless chains a (1, having attached thereto a series of elevating-buckets, D D. The bucketchains run over large pulleys b b on rollershafts, one at the top and the other at the bottom of the bucket-frame O, and around which the buckets run.

At the top of the derrick is a stationary hopper, E, which receives the coal from the buckets D as they run endlessly in the frame or leg 0. This bucket-leg G is thrown out at a longer or shorter angle by merely swinging it out on the wheel at the bottom, and it is folded close to the side of the frame and truck A B by the slots (1, (one in each side of the bueket-frame,)

through which the shaft of the pulley 1) goes.

This slot allows the leg to be raised to a vertical position and closed against the side of the frame A, out of the way when the device is being moved or is not in use.

The buckets are of metal, and of the shape shown in Fig. 3, having flat backs and curved fronts, and with a series of teeth or iron fingers, e e e, projecting from the shovel-edge of the bucket, as shown. These are to aid in picking up the lumps of coal, &c., making the action more sure in loading each bucket. The teeth or fingers are either formed in the edge of the front part of the bucket or are attached thereto, and are formed of the projecting ends of the binding or strengthening strips 6, of metal, on the buckets, as shown in Fig.3. These buckets need not necessarily be of sheet metal, but may be of iron open-work, if desired.

On the side of the derrick A, opposite to the elevating-leg, is hooked or otherwise fastened a conveyer, G, partly shown at y, where it is attached to the frame just at the bottom of the hopper E. (See Fig. 1.) This conveyer is an open frame with raised sides h h, and with rollers i i at top and bottom, around which an endless apron, it, runs, the apron operated bya pulley and belt,th,e latterrunning to the engine that operates the bucket-leg, said engine being generally set on the truck B at one end, but not shown, nor the belts, as not being deemed necessary, in the accompanyingdrawings. On this apron k are fastened a series of rows of teeth, H, to hold the coal on and carry it to the weighhopper H, into which it leads, one end of the conveyer-frame being attached to the hopper, as shown. As soon as the hopper is filled to the amount set on the scale a door, m, is opened and the contents are dumped out.

When the coal is to be spouted directly into a vessel the telescopic spout I is brought into with the buckets D D e e thereon, the conveyer Gr, having the apron k and teeth Z Z, and the In witness whereof I have hereunto signed weigh-hopper H, all arranged and operating my name in the presence of two subscribing conjointly, substantially as and for thepurpose witnesses.
